How to succeed in my life despite the circumstances clearly against me?

I was abused by my brother. He hit my head, kicked me down there, tried to damage my eye and pushed me on the ground. My parents are very biased towards him. I have a part-time job while my brother is training to become a surgeon. He will have a lot of money. I have no decent guy interested in even meeting me, no permanent job, an aging body and abusive parents. My dad punched me on my spine in July and is basically unstable. I am still a virgin and never been on a date. I saved up for plastic surgery but my parents aren’t allowing me to do that. I can’t focus on studies to secure a better job. My clock is ticking and I can’t focus on my career. I’m afraid of remaining single and childless.
I don’t think there’s God. My abuser is living an amazing life while I have no future
